Abstract

1,021,536. Valve and transistor oscillatorinverter circuits. BROWN, BOVERI & CO. Ltd. Dec. 13, 1963 [Dec. 17, 1962], No. 49281/63. Heading H3T. The invention relates to free running inverter circuits utilizing gas discharge or like semiconductor valves and concerns the use of series tuned commutating circuits for switching off the valves. Fig. 2 shows a push-pull type freerunning inverter comprising two gas discharge or like semi-conductor valves 1, 2 which are rendered alternatively conducting by feed-back means, not shown, to produce a square wave output in the secondary winding 5. When valve 1 is fired, current flows through winding 3 to produce the first half-cycle of the output wave. At the same time the capacitor 15 of a tuned circuit 15, 16 charges to a value twice the supply voltage through a circuit comprising diode 11 and the valve 1. Towards the end of the first half-cycle of the inverter output a gas discharge or like semi-conductor valve 7 is fired allowing the capacitor to discharge resonantly. The discharge current flows in the inverse direction through valve 1 until it exceeds the forward current when valve 1 is thus extinguished and the current transfers to diode 9. Shortly afterwards, valve 2 is fired, initiating the second half-cycle during which the voltage across winding 3 causes capacitor 15 to recharge resonantly through inductor 16 and valve 7. When the capacitor is charged to twice the supply voltage current continues to flow through a diode 13 and valve 7, discharging inductor 16. Valve 7 then extinguishes and capacitor 15 discharges resonantly through inductor 16, diode 11 and winding 3. A similar quenching circuit is provided for valve 2. It is stated that inductors 16 and 18 in the quenching circuits could be replaced by inductors having square loop cores and bias windings. Fig. 3 (not shown) illustrates a series-type inverter with a similar quenching arrangement, though a common resonant circuit 15, 16 may be used for the two halves of a circuit (Fig. 11, not shown). The push-pull and series arrangements may be combined to form a bridge-type circuit (Fig. 13, not shown), in which case, by suitably phasing the two branches, particular harmonics can be suppressed.
